  • Surveying system
    Patent number: 7098997
    Abstract: A surveying system that comprises a position relation calculating processor, a correspondence establishing processor, and an image processor is provided. The position relation calculating processor calculates a positional relation between a coordinate system to which measurement information of a measurement point refers and an image of a surveying field, where a staking point is included. The correspondence establishing processor establishes correspondence between three-dimensional position information of the staking point and two-dimensional position information of a point corresponding to the staking point on the schematic image. The image processor superimposes a symbol that indicates the position of the staking point on the schematic image in accordance with the above correspondence.
